Description

Die Erfindung betrifft einen Rolladen für Stauöffnungen in Kastenmöbeln, wobei eine Vielzahl von aneinander angelenkten Rolladenprofilen in seitlichen, U-förmigen Profilführungsschienen geführt sind, wobei in den Rolladenantrieb ein Gewichtsausgleich eingesetzt ist, welcher ein ungewolltes Zu- und Auffahren des Rolladens verhindert, und wobei ein einstückiges, durch gehendes seil vorhanden ist.The invention relates to a roller shutter for storage openings in cabinet furniture, a plurality of hinged roller shutter profiles in side, U-shaped profile guide rails are guided, a weight balance being used in the roller shutter drive is, which prevents an unintentional closing and opening of the roller shutter, and a there is a one-piece, continuous rope.

In der Französischen Patentanmeldung FR 78 09421 ist ein gattungsgemäßer Rolladen beschrieben, der beispielsweise für das Schließen einer Garage oder eines Lastwagenaufbaues verwendet werden kann. Bei dem bekannten Rolladen besteht der Panzer aus einzelnen Panzerelementen, die gelenkig miteinander verbunden sind. Diese Panzerelemente werden von einer horizontalen Antriebswelle bewegt, auf der eine Torsionsfeder gehaltert ist. Antriebswelle und Torsionsfeder sind von einem rohrförmigen Zylinder umgeben, an dessen äußerem Umfang längsverschiebliche Zahnräder angeordnet sind. Diese Zahnräder greifen in die in den einzelnen Panzerelementen gebildeten Aussparungen ein und dienen dabei als Rolladenantrieb beim Aufrollen bzw. Herablassen des Türpanzers.A generic roller shutter is described in French patent application FR 78 09421, for example for closing a garage or a truck body can be used. In the known roller shutter, the shell consists of individual ones Armor elements that are articulated together. These armored elements are moved by a horizontal drive shaft on which a torsion spring is held is. The drive shaft and torsion spring are surrounded by a tubular cylinder the outer circumference of which is arranged longitudinally displaceable gear wheels. These gears engage in the recesses formed in the individual armor elements and serve as a roller shutter drive when rolling up or lowering the door armor.

Der Antrieb dieses Türpanzers erfolgt durch die Antriebswelle über die Zahnräder, die gleichzeitig die Führung des Türpanzers bei den verschiedenen Abrollbewegungen übernehmen. Die seitliche Führung des Türpanzers erfolgt in Führungsschienen, in denen die Endbereiche der einzelnen Panzerelemente während der Bewegungsvorgänge geführt sind. Die Ablaufbewegung des Türpanzers wird durch die auf der Antriebswelle angeordnete Torsionsfeder unterstützt, die als klassischer Gewichtsausgleich dient.This door armor is driven by the drive shaft via the gears at the same time take control of the door armor during the various rolling movements. The door armor is guided laterally in guide rails in which the End areas of the individual armored elements guided during the movement processes are. The outward movement of the door armor is arranged by the on the drive shaft Torsion spring supports, which serves as a classic weight balance.

Das System ist so eingerichtet, daß bei geschlossenem Türpanzer die Torsionsfeder gespannt ist. Wird der Türpanzer zum Öffnen entriegelt, neigt die Torsionsfeder dazu, sich aus dem Spannungszustand in die Ruhelage auszudehnen und versetzt dabei den rohrförmigen Zylinder mit den Zahnrädern in eine in Öffnungsrichtung wirkende Drehbewegung. The system is set up so that the torsion spring is tensioned when the door armor is closed is. If the door armor is unlocked to open, the torsion spring tends to lock itself expand from the state of tension into the rest position and thereby displaces the tubular Cylinder with the gears in a rotational movement acting in the opening direction.

Über die Zahnräder und deren Eingriff in die Aussparungen der einzelnen Panzerelemente wird der Türpanzer in Offenstellung bewegt, wobei die Wirkung der Torsionsfeder bis zur Totalöffnung des Türpanzers durch geringfügiges Nachschieben durch das Bedienungspersonal unterstützt werden kann.About the gears and their engagement in the recesses of the individual armored elements the door armor is moved into the open position, the effect of the torsion spring up to Total opening of the door armor by slight pushing by the operating personnel can be supported.

Das bekannte Rolladensystem mit seinem aufwendigen Antriebsmechanismus ist in erster Linie zum Verschließen großer Öffnungen wie Garagentore, Kraftfahrzeugaufbauten und dergleichen einsetzbar. Bei kleineren Panzergrößen, wie sie beispielsweise beim Verschließen von Kastenmöbeln benutzt werden, ist dieser aufwendige Antrieb unwirtschaftlich und wird vom Markt nicht angenommen.The well-known roller shutter system with its complex drive mechanism is the first Line for closing large openings such as garage doors, vehicle bodies and the same can be used. For smaller tank sizes, such as when closing are used by cabinet furniture, this complex drive is uneconomical and is not accepted by the market.

Ein weiterer gattungsgemäßer Rolladen ist aus der Druckschrift GB-A-270982 bekannt.Another generic roller shutter is known from GB-A-270982.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, auch bei solchen kleineren Öffnungsgrößen einen Rolladen mit Gewichtsausgleich einzusetzen, der technisch weniger aufwendig und damit kostengünstiger einzusetzen ist. Erfindungsgemäß wird dazu vorgeschlagen, daß der Gewichtsausgleich das einstückige, durchgehende Seil ist, welches mit seinen freien Enden an einem Rolladenprofil befestigt ist und über wenigstens zwei Umlenkungen nach Art des Flaschenzugprinzips geführt ist, daß zwischen den Umlenkungen eine Druckfeder angeordnet ist, welche gegenüber der am Seil abgenommenen Kraft ein vielfaches an Bewegungskraft federnd aufnimmt, und daß der Aufbau aus Seil, Umlenkungen und Druckfeder am oberen Rand des Rolladens geführt ist.This is where the invention comes in, which has set itself the task, even with smaller ones Opening sizes use a roller shutter with counterbalance, which is technically less is complex and therefore cheaper to use. According to the invention proposed that the weight balance is the one-piece, continuous rope, which is attached with its free ends to a roller shutter profile and at least two deflections in the manner of the pulley principle is that between the deflections a compression spring is arranged, which is removed from the rope Force absorbs many times more movement force and that the structure made of rope, Deflections and compression spring is guided at the top of the roller shutter.

Beim dem erfindungsgemäßen Rolladen handelt es sich um ein Rolladensystem für Möbelöffnungen, wobei beim Öffnen der Rolladen nicht aufgewickelt, sondern hinter die Schrankrückwand geführt wird. Dadurch geht in der Schrankhöhe kein Platz verloren. Die Mimik für den Gewichtsausgleich hat erfindungsgemäß eine Doppelfunktion, d.h. bei halboffenem Rolladen besteht Gleichgewicht und davon ausgehend wird eine ansteigende Kraft zum Gewichtsausgleich für das Schließen wie für das Öffnen notwendig.The roller shutter according to the invention is a roller shutter system for furniture openings, when the roller shutters are opened, they are not rolled up, but behind the rear wall of the cabinet to be led. This means that no space is lost in the cabinet height. The facial expressions for according to the invention, the weight balance has a double function, i.e. with half open Roller shutters are balanced and based on this, an increasing force becomes Weight balance necessary for closing as well as for opening.

Bei der Öffnungsbewegung wird anstelle der bekannten Kombination Rollfeder-Seilspule erfindungsgemäß ein durchgehendes Seil über Umlenkrollen beruhend auf dem Flaschenzugprinzip eingesetzt. Dabei ist die Druckfeder zwischen den Seilflaschen montiert und bringt ein Vielfaches gegenüber der am Seil abgenommenen Kraft - entsprechend der Kraft-Weg-Gleichung - auf. Die Seilanbindung an den Rolladen ist so gewählt, daß diese sich bei halb offener bzw. halb geschlossener Stellung auf der Höhe des Seilausgangs, also in der Stellung mit der geringsten Seilspannung befindet. In dieser Stellung kommt es dann zum Seilumschlag, d.h. beim vollständigen Öffnen bzw. beim vollständigen Schließen steigt die Seilspannung bis zur maximalen Kraft an. Der besondere Vorteil ist, daß durch die Verwendung von nur einem Seil für zwei Anbindungen sich für diese beiden Anbindungen jeweils die gleiche Zugkraft selbständig einstellt, so daß sie nicht jeweils eingestellt werden muß.During the opening movement, instead of the known combination, the coil spring cable reel According to the invention a continuous rope over pulleys based on the pulley principle used. The compression spring is mounted between the rope bottles and brings a multiple compared to the force removed on the rope - according to the Force-displacement equation - on. The rope connection to the roller shutters is chosen so that this in the half-open or half-closed position at the height of the rope exit, in the position with the lowest rope tension. In this position it happens then for rope handling, i.e. when opening or closing completely the rope tension increases to the maximum force. The particular advantage is that Use only one rope for two connections for these two connections each independently adjusts the same pulling force so that they are not adjusted in each case got to.

Es hat sich als vorteilhaft erwiesen, daß die Umlenkungen in einem Gehäuse laufende, drehbare Rollen sind. Diese Gehäuse-Rollen-Kombination wird im vorliegenden Text auch als "Seilflasche" bezeichnet.It has proven advantageous that the deflections running in a housing, are rotatable rollers. This housing-roller combination is also in the present text referred to as a "rope bottle".

Weiter erscheint es zweckmäßig, daß die Druckfeder mit ihren freien Enden an den zugewandten Endbereichen der Umlenkungen angelenkt ist. Vorteilhaft erfolgt die Befestigung der freien Seilenden an dem Rolladenprofil, welches sich bei halb geöffnetem bzw. halb geschlossenem Rolladen in der Stellung mit der geringsten Seilspannung befindet. Die Führung des Aufbaues Seil-Umlenkungen-Druckfeder ist in einem rohrförmigen Führungselement zusammengefaßt. Bei einem besonderen Einbau kann diese Führung auch in einem Zwischenboden des Kastenmöbels angeordnet sein.Furthermore, it seems appropriate that the compression spring with its free ends on the facing End regions of the deflections is articulated. The attachment is advantageous the free rope ends on the roller shutter profile, which is when half open or half closed roller shutter is in the position with the lowest rope tension. The leadership the construction of the cable deflection spring is in a tubular guide element summarized. With a special installation, this guide can also be in one Intermediate floor of the cabinet furniture can be arranged.

Es läuft nach einer Umlenkung um 90° durch die Öffnung 311 der Abdeckung 31 in das Innere des rohrförmigen Führungselements 3. Innerhalb dieses Führungselementes 3 sind zwei Umlenkungen 4, 5 gelagert, zwischen denen eine Druckfeder 6 angeordnet ist. Zwischen den Umlenkungen 4, 5 verläuft das Seil 7 in einer Rollenführung nach dem Flaschenzugprinzip, wie es zu Fig. 3 im Detail beschrieben ist. Das Seil 7 läuft dann durch die Öffnung 321 der Abdeckung 32 aus dem rohrförmigen Führungselement 3 heraus, wird wieder um 90° umgelenkt und am anderen freien Ende des Rolladenstabes 11 festgelegt. Der Rolladenstab 11 bezeichnet die Mitte des Rolladens, in der dieser sich bei halber Öffnung in der Stellung mit der geringsten Seilspannung befindet.The rope 7 is articulated on the one hand at the left free end of the roller shutter rod 11. It runs after a deflection by 90 ° through the opening 311 of the cover 31 into the interior of the tubular guide element 3. Within this guide element 3 are two deflections 4, 5 mounted, between which a compression spring 6 is arranged. Between Deflections 4, 5, the rope 7 runs in a roller guide according to the pulley principle, as described in detail for FIG. 3. The rope 7 then runs through the opening 321 of the Cover 32 out of tubular guide element 3 is again deflected by 90 ° and fixed at the other free end of the roller shutter rod 11. The roller shutter rod 11 denotes the middle of the roller shutter, in which it is in the position with half the opening with the lowest rope tension.

Aus Fig. 2 wird deutlich, daß der Rolladen 1 über die Tiefe des Schrankes 2 an der hinteren Rückwand geführt ist. Am Rolladenprofil 11 ist der Festpunkt des Seiles 7, welches in das freie Ende 31 des rohrförmigen Führungselementes 3 verläuft. Am Einlauf zur hinteren Aufnahmekammer 23 für den Rolladen 1, die durch die Schrankrückwand 24 und die Abdeckwand 25 geschaffen ist, ist am freien Ende 251 der Abdeckwand 25 die Seilumlenkung 26 angeordnet. Über diese Seilumlenkung 26 verläuft das Seil beim Öffnen des Rolladens in einer Richtung und beim Schließen des Rolladens in der anderen Richtung.From Fig. 2 it is clear that the roller shutter 1 over the depth of the cabinet 2 at the rear Rear wall is guided. At the roller shutter profile 11 is the fixed point of the rope 7, which in the Free end 31 of the tubular guide element 3 extends. At the inlet to the rear receiving chamber 23 for the roller shutter 1, through the cabinet rear wall 24 and the cover wall 25 is created, the cable deflection 26 is at the free end 251 of the cover wall 25 arranged. The cable runs over this cable deflection 26 when the roller shutter is opened one direction and when closing the shutter in the other direction.

Fig. 3 zeigt in der Vergrößerung ein Detail aus dem linken oberen Bereich der Fig. 1. In der Schrankseitenwand 21 ist das Führungsprofil 27 für den Rolladen 1 eingelassen. In dem rohrförmigen Führungselement 3 ist im Bereich des freien Endes die Abdeckung 31 mit der Öffnung 311 für das Seil 7 durch das mechanische Schraubelement 312 fest eingesetzt. Im Abstand davon ist die Umlenkung 4 angeordnet, an der eine Rolle 41 für die Seilumlenkung befestigt ist. Am inneren freien Ende 42 der Umlenkung 4 ist das Ende 61 der Druckfeder 6 angeordnet. Das Seil 7 verläuft nach dem Flachenzugprinzip in einer Umfangsnut der Rolle 41.Fig. 3 shows an enlarged detail from the upper left area of Fig. 1. In the Cabinet side wall 21, the guide profile 27 for the roller shutter 1 is embedded. By doing tubular guide element 3 is in the region of the free end, the cover 31 with the Opening 311 for the rope 7 through the mechanical screw element 312 firmly inserted. in the The deflection 4 is arranged at a distance therefrom, on which a roller 41 for the cable deflection is attached. At the inner free end 42 of the deflection 4 is the end 61 of the compression spring 6 arranged. The rope 7 runs according to the flat tensile principle in a circumferential groove of the roller 41st

In Fig. 4 wird kein Ausführungsbeispiel, sondern eine weitere Möglichkeit beschrieben, das Flaschenzugprinzip bei solchen Schrankrolläden anzuwenden. Es handelt sich hierbei um die Montage von Spannhebeln auf dem Zwischenboden eines Schrankmöbels. Auf dem Zwischenboden 28 des Schrankes 2 ist der bewegliche Spannhebel 8 angeordnet, in den die Zugfeder 81 eingehängt ist. Die Zugfeder 81 ist an ihrem anderen freien Ende mit einem fest angeordneten Montageelement 82 verbunden. Die Zugfeder 81 kann durch Veränderung der Einhängungen in ihrer Kraft eingestellt werden. Am freien Ende 83 des Spannhebels 8 ist der Gelenkspannhebel 84 angeordnet, über den der Spannhebel 8 eine gelenkige Verbindung in Form einer Hubbewegung ausüben kann. Das Seil 7 verläuft hier über eine bewegliche Umlenkrolle 86 am anderen freien Ende 85 des Spannhebels 8 und über eine fixe Umlenkrolle 87 im Bereich der Mittelstellung. Das Seil 7 kann dann bei einem Mittelseil-System durch den Zwischenboden geführt werden, wobei vom Innenraum aus die Seilspannung variiert werden kann.In Fig. 4 no embodiment is described, but a further possibility, the pulley principle in such To use cabinet shutters. This is the assembly of tension levers on the mezzanine of a cupboard. On the intermediate floor 28 of the cabinet 2, the movable clamping lever 8 is arranged, in which the tension spring 81 is suspended. The tension spring 81 is at its other free end with a fixed mounting element 82 connected. The tension spring 81 can by changing the mounts in their Force can be adjusted. At the free end 83 of the clamping lever 8 is the articulated clamping lever 84 arranged, via which the clamping lever 8 an articulated connection in the form of a lifting movement can exercise. The rope 7 runs here via a movable deflection roller 86 other free end 85 of the clamping lever 8 and via a fixed deflection roller 87 in the area the middle position. The rope 7 can then in a middle rope system through the intermediate floor out, the rope tension can be varied from the interior.

In Fig. 5 ist eine Lösung gezeigt, bei der der Rolladen 1 während des Öffnungsvorgangs in einer Schnecke 12 oder einer gebogenen Schiene geführt ist. Das Seil 7 ist in diesem Fall am unteren Rand des Rolladens 1 angebunden, da der Seilumschlag - wie zu Fig. 2 beschrieben - hier nicht notwendig ist. Im Unterschied zu der in Fig. 2 gezeigten Lösung kippt der Rolladen 1 beim Öffnen nicht nach hinten ab, sondern wird in der Schnecke 12 bis zur vollständigen Öffnung geführt.In Fig. 5 a solution is shown in which the roller shutter 1 during the opening process in a screw 12 or a curved rail is guided. The rope 7 is in this case tied to the lower edge of the roller shutter 1, since the rope envelope - as described in FIG. 2 - is not necessary here. In contrast to the solution shown in Fig. 2 tilts the roller shutter 1 does not move backwards when opening, but is in the screw 12 to complete opening.
